  • data.zip

I have droplet diameter and coordinates in a CSV file and I want to draw the all these points in 3d space and later project them on a 2D plane. can someone suggest how can I read this data. Thanks in advance. I'm attaching the file for reference. I'm interested only in droplet diameter and it's coordinates.

I am not exactly certain what you want. One way of plotting them in 3D and also projecting them on a plane is to combine a stem3 plot and a scatter3 plot —

Uz = unzip('data.zip');

% fc = fileread(Uz{1})

fidi = fopen(Uz{1},'rt');

k = 1;

while ~feof(fidi) & (k<=10)

rl{k,:} = fgetl(fidi);

k = k+1;

end

fclose(fidi);

VN = strsplit(rl{4}, ' ');

droplets = readtable(Uz{1}, 'FileType','text', 'HeaderLines',5);

droplets.Properties.VariableNames = VN(2:end-1)

droplets = 4670×20 table

Forgot about getting the variable names for the table. Now added.

Added gray reference plane.

Added colorbar.
